Rintaro Senkawa is a regular
guy in his mid-20s who got a little drunk one night and fell to his death.

But that's just the beginning of Rintaro's story, as he finds
himself unexpectedly in Hell where he meets his guide, the painfully sexy devil
Koyori. Can Rintaro take his situation seriously enough to repent for the sins
of his former life, or is he fated to be eternally tempted, teased, and tortured
by scantily-clad devils with iron spiked clubs?
